Problems solved by technology

However, the density of round sand is high, adding it to the paint and spraying it on the outer wall will increase the weight of the building, and there is a danger of falling off the wall due to wind and sun, and it will also affect the dispersion of the paint.

Abstract

The invention discloses an outer wall coating with a self-cleaning heat-preservation function. The outer wall coating is characterized by being prepared from the following raw materials in parts by weight: 30-35 parts of AP-261 pure acrylic emulsion, 2-3 parts of tungsten boride, 4-6 parts of nano silicon sol, 3-4 parts of glycerin, 1-2 parts of OP-10, 2-3 parts of polyester hollow fiber, 7-10 parts of kieselguhr, 9-11 parts of rutile titanium dioxide, 2-3 parts of sodium dihydrogen phosphate, 6-8 parts of clay, 4-6 parts of superfine talcum powder, 1-2 parts of sodium silicate-bonded sand, 6-8 parts of modified rounded grain mortar and 28-33 parts of water. As an aqueous formula with the pure acrylic emulsion and the like is adopted, and the rutile titanium dioxide is added, the outer wall coating has the self-cleaning function and is resistant to contamination and ultraviolet rays; due to addition of components such as the polyester hollow fiber, the outer wall coating has a certain heat-preservation effect; due to addition of the modified rounded grain mortar, the outer wall coating is light in weight, pleasant in smell, good in dispersion performance, good in waterproof property and attractive in appearance, and the strength of the outer wall coating is improved; the outer wall coating is good in toughness and good in texture.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to an exterior wall coating with self-cleaning and heat preservation functions and a preparation method thereof. Background technique [0002] Nowadays, social coatings have developed towards multi-functionality, green environmental protection, and energy saving. Especially for exterior wall coatings, high weather resistance, green environmental protection, etc. have become the focus of the development of exterior wall coatings today. [0003] Round-grained quartz sand is finely processed from natural quartz sand through multiple processes. The product has high silicon content, is pelletized, has good air permeability, good fluidity, high compressive strength, and is suitable for various purposes. For coatings, suitable particle size ratio, small stacking gaps, saving the amount of resin, and good compatibility with various resins, acid resistance, alkali resistance, ch...
